I am sorry the Pentax has abandoned the AA battery route for their DSLR's.

Pentax has better AA capability than anyone that I know of. The K-500 and K-50 have AA capability with an inexpensive adapter. The top model cameras have grips that can run AA batteries. Does any other manufacturer cater to AA's at all?

Here is what I want in a camera: GPS, AA batteries, high ISO, wifi, ability to run camera from tablet or laptop, and weather sealing.
